During the Total Force Fitness (TFF) Program section of the course, we discussed the importance of leader involvement. Leaders must identify the metrics that will set the right conditions to promote total fitness.
In order to accurately assess the TFF program's effectiveness, metrics must be:

A) challenging.
B) feasible.
C) quantitative.
D) observable.

B) feasible

Explanation:

The Total Force Fitness (TFF ) Program is an integrative and holistic framework to better understand, assess, and maintain the fitness of  the mind and body. The TFF system describes eight essential fields of mind – body which are the physical, dietary, medical, economic, moral, psychological, social, and behavioral.

These eight domains are all relevant and require the attention of unit leaders to ensure unit TFF which is an integral element in the preparation and survival of units in action.

In order to accurately assess the TFF program's effectiveness, metrics must be feasible.

Quantitative

Explanation:

Among the four options given, there are two probable answers, the metrics should be quantitative and feasible also.

Metrics are generally associated with some numbers and if we have numbers then we would be clearly able to calculate the fitness score and hence decide which people are good in fitness level. But also, the metrics must be feasible, it shoudnt be so tough that all people fail the program and we dont come up with any idea as to what percentage is in good range or poor range
